reference to the construction and arrange ment of the means for shifting the said weights.

The present invention has for an object toprovide a novel and simple arrangement and mounting for the weights and the means for shifting the same, and to generally improve the construction of motors of this t e.

For further comprehension of the invention, reference will be had to the following description and accompanying drawings, and to the appended claims in which the various'novel features of the invention are more particularly set forth. v

In the present embodiment of the invention, the machine comprises a pair of side frames 10 each comprising a longitudinally extending top horizontal member and a series of legs 10, the latter being adapted to be bolted to the floor, or other bed of the machine, as indicated at 11.

Supported in suitable bearings 12 midway between opposite ends of the frames 10 1S a transverse shaft 13. Upon this shaft 13, between the side frames 10 is suitably fixed the hub 14 of a Wheel 15 which carries the shift- Specification of Letters Patent.

ing weights... The weights are slidably mounted on a series of radial rods 16 fixed at inner and outer ends respectively to the hub and rim of the wheel 15. These rods are preferably disposed between and in alternation to the spokes 14 of the wheel.

The weights are shown at 17 and are in the form'of sleeve like members through which the rods pass freely. Mounted on the hub 14 in a common axial disposition with the respective rods 16, are a series of solenoids 18 through the hollow centres or core apertures, of which the rods lfiextend, the rods being smaller in diameter than the said core apertures of the solenoids. For convenient mounting of the solenoids on the hub 14L the circumference of the latter is formed of polygonal shape to present a series of flat surfaces to which the solenoid heads may be screwed or otherwise secured. The cores of the solenoids are shown at 20, being in the form of cylindrical members freely surrounding the rods 16 inwardly of the weights and connected to the latter by rigid straps 21. The inner ends of these cores are preferably tapered as at 20.

The solenoids 18 act to drawthe weights 1? toward the centre of the wheel 15, while the weights are shifted to their outer positlons as the wheel rotates by engagement with a pair of circular tracks arranged eccentric to the wheel 15, one on each side thereof and preferably mounted in a manner to permit of adjustment to move their centres toward or away from the axis of the wheel.

These tracks consist of a pair of rings 22, fixed by suitable brackets such as 23, to a pair of skeleton-formed rectangular slides 24- which are mounted on the side frames 10 to be adjustable in unison longitudinally thereof. To this end, a pair of horizontal guide rails 25 are'bolted to the inner faces to the legs 10 of the side frames and having the slides 24 resting thereon; cooperating tongue and groove guide elements 26 being formed on the contacting faces of the slides and rails to guide the slides on the rails.

legs fixed to the slides 24: by bolts such as 31 and has its web formed with a boss 32 through which is threaded a screw 33 swiveled as at 3-1- in a U-bracket 35 bolted to and. between the side frames 10. The screw 33 has a handwheel 36 fixed thereto for purposes of rotation.

The means for effecting engagement between the track rings 22 and the weights 17 comprises a second pair of rings 38 enclosing the rings 22 and rotating on the latter, having an anti-friction bearing therewith as indicated at 39. These outer rings 38 are rigidly fixed to the weights 17 by suitable means such as the rods 10 projecting from sockets in the latter and secured at their outer ends by screws 4-1 to the rings 38.

As indicated by the wiring connections 45 and -16 in Figure 1, the solenoids 18 are preferably of the split coil type to increase their power, these solenoids being energized at the proper times through the following means:

Mounted on the inside of one of the side frames 10 is a vertical plate 50 of. insulating material having an aperture 51 of larger diameter than the shaft 13 through which the latter passes. Fixed to the inner face of this plate 50, to be flush therewith, is a segmental contact member 52 which extends through an arc corresponding in length and position to the are of rotation during which each solenoid is energized. This contact 52 has an integral tail piece 53 to which the end of one of the main leads 54: is connected.

Fixed to the shaft 13, adjacent the plate 50, is a collar 56 of insulating material carrying a series of slidable contact studs 57 pressed by springs 58 against the plate 50, these contact studs having the wiring connections 4:53 to one side of the respective solenoid coils 18 attached thereto. Fixed on the shaft 13 on the opposite side of the hub 14-. to the collar 56 is a second insulating collar 60 on which is mounted a metal ring 61 to which the wiring connections 416 from the opposite sides of the solenoid coils lead. Upon this ring 61 a stationary brush 653 bears, to which is connected the other main lead 63. Pulleys or fly wheels 64 may be mounted on opposite ends of the shaft.

It is believed that the manner of operation of my improved motor will be readily understood from the above description. With the tracks 22 and their enclosing rings 38 in the eccentric position as shown, the weigl'its 17, which move with the rings 38, are considerably further from the axis of rotation of wheel 15 on one side (as indicated in the drawings, the left) than on the other, producing a preponderance of turning leverage on one side of the shaft 13 which will cause the latter to rotate, and with it wheel 15 as indicated by the arrows in Figures 3 and During rotation, the studs 57 successively come into contact with the lows contact segment 52, each pin as it engages the segment closing the circuit through the corresponding solenoid, the current passing through main lead 434i, contact 52, stud 57, split solenoid connection 45, the solenoid coils, split solenoid connection 16, ring 6]., brush 62 and main lead (33. Each solenoid 18 remains energized as long as the corresponding stud 57 engages the contact segment 52, the length of this segment being greater than the spacing of these studs so that one of the solenoids is energized at all times.

In Figure 3 of the drawings I have inclicated by the line A the relative length and position of the are through which the solenoids a e energized, which are commences at a point where the weights 17 and solenoid cores 20 are approacl'iing that side of the tracks 22 which. is nearest the axis of the wheel 15 so that the attraction of the cores 20 by the energizing of the solenoids will both act to draw the weights 17 inwardly toward the centre on that side (leaving a preponderance of turning leverage on the opposite side due to the weights on the opposite side being moved outwardly by tracks 22) and also, by reason of the oblique relation of this portion of the tracks 22 to the intersecting radii of the wheel 15, the pull exerted by the solenoid will result in a turning movement being exerted on the rings 38 and in consequence on the wheel. By this combined action of the weights 17 and of the tracks 29, and rings 38 a continuous rotation of the shaft and wheel is obtained. The are through which the solenoids are energized preferably terminates just short of the point where the tracks are nearest the shaft 13, leaving the weights 17 free to be carried outward as they move toward the opposite side of the wheel.

Having thus described my invention what I claim as new and desire. to secure by Letters Patent of the United States is as fol- 1.
